Sorry, I don't know the brand, but about 1963 I saw this done to inspect
the spot welds in an epoxy potted module on a satellite command decoder
module. It took about two weeks of soaking in a rather vile solution
and we had to pick at it from time to time to flake off the softened
epoxy.
Don't give up, it is (was) out there somewhere. As I recall we were
buying our stuff from Dow-Corning at that time.
Also, consider X-Raying it.
